Thank you for viewing. Yatterman McDonald's Happy Set Oshioiki Bomb (Punishment Bomb) - Unopened. According to the package, it's probably from around 2010. As written on the package, there's an ON/OFF switch. Even unopened, you can switch it, so I kept it in the OFF position. Even now, when I turn it ON and press the yellow switch, it says "Oshioiki da be~" (Time for punishment!). The blue part seems to be designed to pop out when you press the switch while it's clipped to the bomb. Unopened, and the batteries still work, but it's old, so please understand this before purchasing. If you have any questions, please ask. Please refrain from purchasing if you are overly concerned about details.
